You have wanted a child for a long time and adopted a child, but there is a problem... he is quite anxious , although it hardly shows .Your child , Sigma , seems to have trouble communicating with other children. He's not shy , but often talks and asks questions. He prefers to play alone with toys rather than join his classmates. Perhaps you should talk to him to see if there's anything behind the child's reserved appearance.-...Sigma is silent and sits in his room on the floor
